Origin

Swalot's appearance may be based on a single, giant poison gland. Swalot might be based upon a generic organism that uses pseudopodia.

It has been compared to a blobfish by many fans, but the popular blobfish photograph is copyright 2003, which is shortly after the Generation III games was released, and shows a front view of a heavily damaged specimen.

Name origin

Swalot may be a play on the phrase, "swallow a lot," as in consuming a large amount of food or drink.

Marunoom may be a combination of 丸呑み marunomi (swallowing whole) and nomu (swallow or gulp).
